- Lindsey Graham (R) seeks his 5th Senate term in 2026 — rated Safe Republican. Trump won South Carolina by 17.9 points in 2024 (58.2% vs. 40.4%).
- Graham survived a record-breaking $130M Democratic challenge in 2020 (Jaime Harrison) and still won by 10.2 points — illustrating the structural Republican ceiling in SC statewide races.
- Graham’s national foreign policy profile (Armed Services Committee, Senate Judiciary) and decades of incumbency make him nearly invulnerable in this state. Note: Tim Scott (Class 3) is not up until 2028.
- South Carolina's growing Charleston and Columbia suburbs have Democratic trends, but rural and Upstate SC Republican dominance easily offsets any urban gains.
Lindsey Graham: Profile
Lindsey Graham is one of the longest-serving and most recognizable Republican senators in America. First elected to the Senate in 2002 — winning an open seat vacated by the legendary Strom Thurmond — Graham has been re-elected three times by comfortable margins. He is a former US Air Force Reserve JAG officer (Judge Advocate General Corps) and served as one of the House managers during the Clinton impeachment in 1998, helping to build his national profile before his Senate career.
Graham has chaired or served in senior positions on the Senate Judiciary and Armed Services Committees, making him a central figure in both judicial confirmations and foreign policy debates. He is known as a foreign policy hawk who has supported US military involvement in Iraq, Afghanistan, Libya, and Syria and has been one of the Senate’s most consistent advocates for strong defense spending. His political transformation — from one of Trump’s harshest critics in 2016 to one of his closest allies — is one of the defining stories of the Republican Party’s Trump era.
In 2020, Graham survived what appeared to be a genuine challenge from Democrat Jaime Harrison, who raised a record-breaking $130 million and generated national attention. Despite the fundraising disparity, Graham won by 10.2 percentage points — a result that illustrated both the power of incumbency in a deep-red state and the limits of money in highly partisan environments. In 2026, Graham faces Democratic challenger Dr. Annie Andrews, a pediatrician whose campaign centers on healthcare and vaccine access. Early polling (Impact Research, March 2026) shows Graham leading 47%–42% — tighter than most past SC cycles. Independent voters break for Andrews by 19 points. Cook Political Report and Sabato still rate the race Safe Republican, reflecting South Carolina’s structural lean: Trump won the state by 17.9 points in 2024 (58.2% vs. 40.4%).

Key Issues
Foreign Policy & Defense
Graham has been one of the Senate’s most consistent voices for US military engagement abroad. He supported the Iraq and Afghanistan wars, pushed for arming Ukraine, and has taken an aggressive stance on Iran’s nuclear program. As a senior Armed Services Committee member, defense spending and military readiness are signature priorities.
Judiciary & Courts
Graham played a central role in the confirmations of Justices Gorsuch, Kavanaugh, and Barrett. He has chaired the Senate Judiciary Committee and has been a key player in shaping the federal judiciary for a generation. Judicial appointments remain a rallying issue for his conservative base in South Carolina.
Immigration & Border
Graham has had a complicated immigration history — he co-authored the bipartisan Gang of Eight immigration reform bill in 2013 and more recently worked on bipartisan border security legislation. While sometimes breaking with hardliners, he consistently supports stricter enforcement and border wall funding, aligning with his base in a state where immigration polls as a top issue.
